BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to convertible furniture construction and, more particularly, to furniture construction that can be converted from a table or desk to a bed and vice versa.

2. Description of Related Art

Tables and beds have become necessities. However, conventional tables and beds can occupy significant space, which can be limited. For example, in many apartments, offices, school dormitories, etc., there may not be enough room for both a bed and a table. In addition, even when sufficient room exists, tables (or, alternatively, desks) and beds can be costly, which can limit the ability of some purchasers to purchase these items. In other settings, such as an office, it may not be appropriate to have a bed openly displayed during the day, even though the occupant may be required to work late or sleep at the office on occasion. Thus, there is a need for a furniture construction that can function as both a desk or table and a bed.

BRIEF SUMMARY OF THE INVENTION

The present invention provides a furniture construction, and an associated method of manufacture, that can be converted from a bed to a table or desk and vice versa. As used herein, the terms “table” and “desk” are used interchangeably to refer to a relatively planar support surface. According to one embodiment, the furniture construction includes a support structure having a pair of end members. The furniture construction also includes a bed frame movably connected to the end members of the support structure so that the bed frame can be moved between an inoperative first position and an operative second position. In one embodiment, the inoperative first position of said bed frame is substantially vertical and the operative second position of said bed frame is substantially horizontal. The furniture construction includes a table movably connected to the end members of the support structure so that the table can be adjusted between an operative first position and an inoperative second position. The bed frame and the table are structured such that when the bed frame is in the operative second position the table is in the inoperative second position, and when the table is in the operative first position the bed frame is in the inoperative second position. Advantageously, the bed frame and the table are decoupled from one another to provide for flexibility as to how the two components are positioned, as well as to decrease the amount of force necessary to move each component from its operative position to its inoperative position, and vice versa, thereby providing greater ease of use and safety to the user. In one embodiment, the furniture construction includes at least one biasing mechanism structured to bias the table from the inoperative second position toward the operative first position. For example, the biasing mechanism can include a piston and cylinder assembly. In another embodiment, the furniture construction includes a locking mechanism to maintain the bed frame in second operative second position. In still another embodiment, the bed frame is frictionally received between the table and the support structure.

According to another embodiment, the furniture construction includes a support structure having a pair of end members. The furniture construction also includes a bed frame comprising a pair of end members and a planar member extending therebetween, each of the end members of the bed frame being rotatably connected to one of the end members of the support structure so that the bed frame can be rotated between an inoperative first position and an operative second position. The furniture construction includes a table comprising a planar member, the planar member of the table being adjustably connected to each of the end members of the support structure so that the table can be adjusted between an operative first position and an inoperative second position. The bed frame and the table are structured such that when the bed frame is in the operative second position the table is in the inoperative second position, and when the table is in the operative first position the bed frame is in the inoperative second position.

According to yet another embodiment, the furniture construction comprises a support structure having a pair of end members defining a space therebetween. The furniture construction also includes a bed frame movably connected to the end members of the support structure so that the bed frame can be moved between an inoperative first position and an operative second position. The furniture construction includes a desk slidably disposed between the end members of the support structure so that the desk can be slid into and out of the space defined therebetween.

The present invention also provides a method of constructing a furniture construction. In one embodiment, the method includes providing a support structure having a pair of end members. A bed frame is movably connected to the end members of the support structure so that the bed frame can be rotated between an inoperative first position and an operative second position. In one embodiment, the inoperative first position of the bed frame is substantially vertical and the operative second position of the bed frame is substantially horizontal. A table is movably connected to the end members of the support structure so that the table can be adjusted between an operative first position and an inoperative second position. The bed frame and the table are structured such that when the bed frame is in the operative second position the table is in the inoperative second position, and when the table is in the operative first position the bed frame is in the inoperative second position.

According to another embodiment, the method comprises providing a support structure having a pair of end members defining a space therebetween. A bed frame is movably connected to the end members of the support structure so that the bed frame can be rotated between an inoperative first position and an operative second position. A desk is slidably positioned between the end members of the support structure so that the desk can be slid into and out of the space defined between the pair of end members.

Thus, the present invention provides a furniture construction that can function as both a desk or table and a bed and that is structured to provide flexibility, ease of use and safety for the user.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown. Indeed, these inventions may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.

Referring to FIGS. 1 and 2, there is illustrated a furniture construction 9, according to one embodiment of the present invention. The furniture construction 9 comprises a support structure 10, a bed frame (also referred to herein as a “bed”) 20, and a table 30. The support structure 10 comprises a pair of end members 11 and, according to one embodiment, at least one connector or side member 12 extending therebetween. The connector 12 of the support structure 10 can include a second bed frame 20 b extending between the pair of end members 11, as illustrated in FIGS. 1 and 2. According to other embodiments (not shown), the connector 12 can comprise drawers, shelving, a canopy, or one or more elongate members extending between the end members 11 to provide support. In other embodiment, lighting can be attached to or mounted within the connector 12. The connector 12 can be welded to the end members 11 and/or attached using suitable fasteners. The end members 11 can be constructed in a variety of configurations depending on the desired aesthetic appearance (e.g., tubular members having square, circular, oval, hexagonal, etc. cross-sectional configurations). In another embodiment (not shown), the support structure 10 of the furniture construction 9 comprises only a pair of end members 11 (i.e., with no connector 12 extending therebetween). The support structure 10 is structured to support the bed frame 20 and table 30 and can be constructed of any suitable material, including, without limitation, metal, plastic and/or wood.

According to one embodiment of the present invention, as illustrated in FIGS. 2 and 4-6, the bed frame 20 includes a pair of end members 21, a pair of lateral members 22 and a planar member or support 23 extending therebetween. The end members 21 and lateral members 22 can be welded together and/or attached using suitable fasteners. Similarly, the planar member 23 can be secured (although not require) to the end members 21 and lateral members 22 by welding or using suitable fasteners. In one embodiment, the bed frame 20 includes a plurality of slats 24 extending between the lateral members 22 that are structured to provide support to the planar member 23. The end members 21 and lateral members 22 can have a variety of configurations depending on the desired aesthetic appearance. The bed frame 20 is structured to support a predetermined amount of weight, including the weight of a mattress (not shown), as well as the weight of a person or persons sitting or sleeping on the bed frame. The end members 21 and lateral members 22 can be constructed of any suitable material, including metal, plastic and/or wood. The planar member 23 can comprise wood, metal, or plastic; or a wood, plastic or metal frame construction having slats, spring wire, canvas, a wire or fabric mesh or the like extending therebetween, as is well known to those skilled in the art. For example, the planar member 23 can comprise a standard box spring. According to one embodiment, as illustrated in FIG. 1, the underside 25 of the bed frame 20 can include an appropriate material 26, such as paneling, fabric or corkboard, that will conceal the bed frame when the bed frame is in the inoperative first position and that provides the user of the table 30 with a surface to post notes, pictures, etc. and/or that is aesthetically coordinated with the table or support structure 10.

The end members 21 of the bed frame 20 are rotatably attached to, and secured between, the end members 11 of the support structure 10 so that the bed frame can be rotated from the inoperative first position illustrated in FIG. 1 to the operative second position illustrated in FIG. 2, and vice versa. According to one embodiment, as illustrated in FIGS. 2 and 4-6, the end members 21 of the bed frame 20 are rotatably attached to, and secured between, the end members 11 of the support structure 10 using a pair of rotatable connectors 27. For example, the rotatable connectors 27 can comprise cylindrical members or shafts with suitable bearings structured to fit within corresponding apertures defined by the end members 21 of the bed frame 20 and the end members 11 of the support structure 10.

Preferably, at least one end member 11 of the support structure 10 includes a mechanism to assist the user in rotating the bed frame 20 from the inoperative first position illustrated in FIG. 1 to the operative second position illustrated in FIG. 2. For example, according to one embodiment, as illustrated in FIGS. 5 and 6, at least one end member 11 of the support structure 10 includes a pneumatic or hydraulic cylinder 14 that extends between the end member 11 of the support structure 10 and the end member 21 of the bed frame 20. The cylinder 14 can be secured to the end member 11 of the support structure 10 and the end member 21 of the bed frame 20 using suitable fasteners or by welding. The cylinder 14 assists the user in rotating the bed frame 20 from the inoperative first position illustrated in FIG. 1 to the operative second position illustrated in FIG. 2, and vice versa, by providing resistance against the weight of the bed frame 20 as the bed frame is rotated into, and away from, the operative position.

According to one embodiment of the present invention, as illustrated in FIGS. 1, 3, 4, 7 and 8, the table 30 includes a pair of end members 31, a pair of lateral members 32 and a planar member or support 33 extending therebetween. The end members 31 and lateral members 32 can be welded together and/or attached using suitable fasteners. Similarly, the planar member 33 can be secured to the end members 31 and lateral members 32 by welding or using suitable fasteners. While not required, as illustrated in FIG. 1, the table 30 may also include a back splash 34, which can be secured to the planar member 31 and/or corresponding lateral member 32 by welding and/or using suitable fasteners. Although referred to herein as a “table,” as noted above, the planar member 31 can function as a desk or other work surface for the user of the furniture construction 9. The table 30 is structured to support a predetermined amount of weight. The end members 31, lateral members 32 and planar member 33 can be constructed of any suitable material, including, without limitation, metal, plastic and/or wood.

The end members 31 of the table 30 are slidably attached to, and secured between, the end members 11 of the support structure 10 so that the table can be slid from the inoperative second position illustrated in FIG. 2 to the operative first position illustrated in FIG. 1, and vice versa. According one embodiment, as illustrated in FIGS. 2, 7 and 8, the table 30 includes a pair of male support members 37, each of which slidably engages a corresponding female receptacle 38 attached to, and secured to, a corresponding end member 11 of the support structure 10.

Preferably, at least one end member 11 of the support structure 10 includes a mechanism, such as a biasing mechanism, to assist the user in sliding the table 30 from the operative first position illustrated in FIG. 1 to the inoperative second position illustrated in FIG. 2, and vice versa. For example, according to one embodiment, as illustrated in FIGS. 10A and 10B, at least one of the female receptacles 38 of the end members 11 of the support structure 10 can include a pneumatic or hydraulic cylinder 15 that connects the male support member 37 and the corresponding female receptacle 38. In the illustrated embodiment, the cylinder 15 is shown mounted to the female receptacle 38 with the piston extending to the male support member 37. According to another embodiment, the cylinder 15 is mounted to the male support member 37 with the piston extending to the female receptacle 38. The cylinder 15 (and corresponding piston) can be secured to the male support member 37 and female receptacle 38 of the corresponding end member 11 of the support structure 10 by welding or using suitable fasteners. The cylinder 15 assists the user in sliding the table 30 from the operative first position illustrated in FIG. 1 to the inoperative second position illustrated in FIG. 2 and vice versa by providing resistance against (i.e., is biased against) the weight of the table as the table is slid into the inoperative position and operative position, respectively.

Referring to FIG. 9, the end members 31 of the table 30 each preferably define a groove 35 that is structured to receive the corresponding end member 21 of the table 20. When the bed frame 20 is in the operative second position and the table is in the inoperative second position, as illustrated in FIG. 2, each end member 21 of the bed frame 20 frictionally engages the corresponding groove 35 to thereby prevent the table from sliding from the inoperative second position to the operative first position.

Referring further to FIGS. 1 and 2, when the furniture construction 9 of the present invention needs to be used as a table 30 (as shown in FIG. 1), the bed frame 20 is rotated approximately 90 degrees from the operative second position illustrated in FIG. 2 to the inoperative first position illustrated in FIG. 1. As illustrated in FIG. 6, the bed frame 20 and the table 30 move independently of each other (i.e., the bed frame and table are not coupled together). Advantageously, decoupling the bed frame and the table from one another provides flexibility as to how the two components are positioned, as well as decreases the amount of force necessary to move each component from its operative position to its inoperative position, and vice versa, thereby providing greater ease of use and safety to the user. Thereafter, as illustrated in FIGS. 1, 7 and 8, the table 30 is lifted upwards such that the male support members 37 slide into the female receptacles 38. As illustrated in FIG. 1, the furniture construction 9 includes a locking mechanism 39, such as a pin configured to be received within an aperture, to maintain the table 30 in the operative first position.

Referring further to FIGS. 2 and 6-8, when the device of the present invention needs to be used as a bed 30 (as shown in FIG. 2), the table 30 is slid downwards into its inoperative second position such that the male support members 37 slid within the female receptacles 38. A predetermined amount of force preferably must be applied to the table 30 in order to move the table 30 from the operative first position. Once the table 30 is moved into the inoperative second position, the bed frame 20 can be rotated approximately 90 degrees from the inoperative first position illustrated in FIG. 1 to the operative second position illustrated in FIG. 2.

Referring to FIGS. 11 and 12, there is illustrated a furniture construction 90, according to another embodiment of the present invention. The furniture construction 90 comprises a support structure 110, a bed frame 120, and a table 130. The support structure 110 comprises a pair of end members 111 and, according to one embodiment, at least one connector or side member 112 extending therebetween. As noted above, the connector 112 of the support structure 110 can include a second bed frame 120 b extending between the pair of end members 111. The connector 112 can be welded to the end members 111 and/or attached using suitable fasteners. The end members 111 can be constructed in a variety of configurations depending on the desired aesthetic appearance. In another embodiment (not shown), the support structure 110 of the furniture construction 90 comprises only a pair of end members 111 (i.e., with no connector 112 extending therebetween). The support structure 110 is structured to support the bed frame 120 and table 130 and can be constructed of any suitable material, including, without limitation, metal, plastic and/or wood.

According to one embodiment of the present invention, as illustrated in FIGS. 12 and 14-16, the bed frame 120 includes a pair of end members 121, a pair of lateral members 122 and a planar member or support 123 extending therebetween. The end members 121 and lateral members 122 can be welded together and/or attached using suitable fasteners. Similarly, the planar member 123 can be secured to the end members 121 and lateral members 122 by welding or using suitable fasteners. In one embodiment, the bed frame 20 includes a plurality of slats 124 extending between the lateral members 122 that are structured to provide support to the planar member 123. The end members 121 and lateral members 122 can have a variety of configurations depending on the desired aesthetic appearance. The bed frame 120 is structured to support a predetermined amount of weight, including the weight of a mattress (not shown), as well as the weight of a person or persons sitting or sleeping on the bed frame. The end members 121 and lateral members 122 can be constructed of any suitable material, including, without limitation, metal, plastic and/or wood. As discussed above, the planar member 123 can comprise wood, wire mesh or spring wire, canvas, or other materials that have sufficient strength. The slats can be formed of metal, wood, plastic, wire, rope, or other materials that have sufficient strength.

The end members 121 of the bed frame 120 are rotatably attached to, and secured between, the end members 111 of the support structure 110 so that the bed frame can be rotated from the inoperative first position illustrated in FIG. 11 to the operative second position illustrated in FIG. 12, and vice versa. According to one embodiment, as illustrated in FIGS. 12 and 14-16, the end members 121 of the bed frame 120 are rotatably attached to, and secured between, the end members 111 of the support structure 110 using a pair of rotatable connectors 125. For example, the rotatable connectors 125 can comprise cylindrical members or shafts with suitable bearings structured to fit within corresponding apertures defined by the end members 121 of the bed frame 120 and the end members 111 of the support structure 110.

Preferably, at least one end member 111 of the support structure 110 includes a mechanism to assist the user in rotating the bed frame 120 from the inoperative first position illustrated in FIG. 11 to the operative second position illustrated in FIG. 12. For example, according to one embodiment, as illustrated in FIGS. 15 and 16, at least one end member 111 of the support structure 110 includes a pneumatic or hydraulic cylinder 114 that extends between the end member 111 of the support structure 110 and the end member 121 of the bed frame 120. The cylinder 114 can be secured to the end member 111 of the support structure 110 and the end member 121 of the bed frame 120 using suitable fasteners. The cylinder 114 assists the user in rotating the bed frame 120 from the inoperative first position illustrated in FIG. 11 to the operative second position illustrated in FIG. 12 by providing resistance against the weight of the bed frame 120 as the bed frame is rotated into the operative position.

According to one embodiment of the present invention, as illustrated in FIGS. 11, 13, 17 and 18, the table 130 includes a pair of end members 131, a pair of lateral members 132 and a planar member or support 133 extending therebetween.
